Thi'sapplication' is a 'division 'of my application for Sausage linker Serial N0f1253148ffiled February 1937, which has issued "as'Patent No. 2,168,693, datedAugust 8.1939;

Oneof the objects of thei-nventi on'is to provide apparatus for use in s'tufling and linking sausage. 7 1 I Another object of the-invention i'st'o provide anovel rotatable sausage s'tufling nozzleadapted to provide resistance to the slippage-of casing material passed from the nozzle in 'the stufiing operation.

Other objects of the invention will be apparent from the I description and 'claimsi which follow. In the draw'ings 'thesimilar reference characters in the several figures" indicate'similar parts. g y

Figure 6 is a sectional View taken on line 6- of Figure 5. 7

Stuffing nozzle l is mounted as by threads 2 on rotating spindle 3 provided with passage 4 through its center communicating the passage 5 of nozzle 1 with sausage stuffer outlet 6.

Spindle 3 is rotatably mounted in bearings 1 and 8 in housing 9. Spindle 3 may be rotatably driven by any suitable means as for example, worm wheel !9, firmly secured to the spindle at H. Worm wheel l0 engages with worm l2, driven by motor l3. Spindle 3 extends through housing 9 into stuihng box I4 integral with bracket l5 supported by housing 9. Stuffing box l4 may be fastened to the stuffer outlet by any suitable device such as a threaded ring [6. The rotatable nozzle illustrated in Figure 1 may be attached to any convenient source of sausage meat. Figures 2 and 3 illustrate a stuffing nozzle which may be employed with the apparatus. The stuffing nozzle is shown in these figuresas split into a number of segments IT by narrow slots IS. The tension of sausage material forced through the stuffing horn causes the individual segments nto; move outwardly "from the center of the nozzle' 1. I. 5" 7. Fit. l Q

1 A cap 'IB maybe-'placedover'the end of the expanding nozzlef20 tofacilitate threading a casing'on the nozzle. After the casinghas' been placedfon the nozzleythe cap is removed. The expanding type of "nozzle 'i flprovides 2. driving force between the"surface ofthe-nozzle and the casing to insure]that the c'asing rotates with the nozzleduring the stum'ng operation.

' In'empl'oyi'ngthe apparatus shown in Figure 1, a suitable length ofeasing is placed upon nozzle l and-'motor"l3 startedl Sausage meat under pressure is admitted through outlet 6 'to passage 4 and entersno'z'zlel throughpassage 5'. If one end of the casing' is'cl'os'ed over the end of the stufiingfnozzle, a length bisausage-will -start to form. By re'ason of the rotati'onof the nozzle throughthe turning offivormgea'r. H) by worm l2, the" length of forming 'sausage coming off the horn will rotate. When a suitable length of sausage has issued from the nozzle, the operator pinches the casing, forming. a link of sausage. The length of sausage which has been formed up to the point of pinching the casing will stop rotating. That portion of the length of sausage which is being formed will continue to rotate, resulting in the formation of one end of a link at the point of pinching.

A convenient gauge 25 as shown in Figure 5 may be arranged to aid the operator in determining the pointsat which to pinch the casing to obtain a series of links of the desired length. To secure the best results in a device of this type, 7 it i necessary that the rate of discharge of sausage meat into the Ca ing be uniform. Apparatus for carrying out this function is illustrated in Figure 5, wherein the outlet 6 communicates with stuffer cylinder 26 containing sausage meat 21, Piston 28 is adapted to slide within cylinder 26. The sausage meat may be introduced under pressure to stufiercylinder 26 through pipe 29,

' controlled by a stuffer valve 30. In ordinary operations the capacity of cylinder 26 is approximately fifty pounds of sausage meat. Piston 28 is carried by a threaded stem 3 I, the screw thread of which coact with a mating thread in Worm Wheel 32. When worm wheel 32 is rotating in its bearings 33 and 34, rod 3| will move up or down depending upon the direction of rotation of the Worm wheel. A ball-thrust bearing is provided at 35. The piston rod 3| is slotted as shown at 35. Slot 36 coact-s with a sliding key 31 held in collar 38 to prevent rod 3| turning with the motion of worm wheel 32. Worm wheel 32 is turnedby worm 39 driven by any suitablesource of power, as, for example, a reversible electric motor which may be used to raise or lower the pis-' of the device will be understood by reference to Figure 5. Assuming that chamber 26 is empty, 5

the operator opens valve 30 which will communicate chamber 26 with a sausage meat reservoir as shown. The driving motor operating worm 39 is set to draw piston 28 away from the closedendig of the cylinder 26. As the piston moves, the space the upper end of its travel, the driving motor may be stopped and valve 30 closed. A sausage casing 23 may then be placed on stufiing nozzle 1 and motor l3 started. Simultaneously, the drivin motor worm 39 is started to cause piston 28 to be driven downwardly. The operator now pinches the end of the casing a short distance from theend of the nozzle as at 42. Sausage meat issuing from nozzle l at a uniform rate will form lengths such as link 40. As each neck 42 passes gauge point 43, the operator again pinches the casing at 42, starting a new link. 7

The speed relation between rotating nozzle l and the rate of extrusion of the sausagemeat should be such as to give from two to three twists of; the casing between each link. i

It' will be appreciated that an apparatus such as shown in Figure 5 may be constructed compactly such that a number of'such devicesmay be fed from a single sausage meat" reservoir.
